2024 NFL Draft top 150 prospect rankings: Biggest risers and fallers, as Marvin Harrison Jr., 3 QBs in top 15

The 2024 NFL Draft prospect rankings are a ball of clay that hasn't yet taken its final shape, but will be molded to a finished product on April 25. CBSSports.com's Ryan Wilson, Chris Trapasso and myself compiled our rankings to formulate an updated aggregate of the top 150.

College football is abuzz with transfer additions and defections since the portal opened to underclassmen Monday. The NFL Draft declaration deadline is not for another month so players still have time to make a decision -- possibly changing their minds once or twice over. As a result, the list may include players who are currently saying they intend to return to school or have entered the transfer portal; Duke quarterback Riley Leonard, for example.

Without further ado, here are the updated Top-150 prospect rankings for the 2024 NFL Draft as college football's regular season ends, with a breakdown of the big risers and fallers below:

Risers

QB Jayden Daniels, LSU

Daniels is a Heisman Trophy finalist after leading the Tigers to a 9-3 record. He has shown improved decision-making and enough arm strength to succeed at the next level. When the play breaks down, the Arizona State transfer is able to use his legs to extend plays and find outlets late in the down. Daniels has a large body of work at the college level so the transition to the NFL should be a bit smoother; similar to Brock Purdy and less like Trey Lance.

CB Quinyon Mitchell, Toledo

Mitchell shares some of the traits that allowed Illinois' Devon Witherspoon to rise a year ago. He is a filled-out cornerback with good top end speed. His competitive spirit is what will excite prospective NFL teams. Mitchell does a good job of getting his eyes back to the ball -- as evidenced by six interceptions over the past two years -- and playing it on arrival. He is willing to play downhill and provide run support. 

OT Taliese Fuaga, Oregon State

Fuaga is part of an Oregon State team whose head coach was recently hired at Michigan State. The program had done a good job of developing players like Joshua Gray, Luke Musgrave and Fuaga. The latter is a massive human being who serves as a road block at right tackle for opposing PAC-12 blockers. He has great upper body strength and will finish plays. Despite not being a contender to win any foot races, Fuaga does a great job of adjusting his hands and feet when engaged. 

Fallers

IOL Cooper Beebe, Kansas State

There is nothing bad to say about Beebe. He has been a personal favorite since watching him play as a sophomore. The Kansas City native plays with an edge and is not afraid to take plays to the ground. He is a sound player and his slippage has more to do with others rising up the ranks. In a relatively weak interior offensive line draft, Beebe projects as one of the best.

QB Riley Leonard, Duke

Leonard has entered the transfer portal and will probably play next season at Notre Dame. IrishIllustrated.com, part of the 247Sports network, is reporting that Leonard will take a visit to South Bend later this week. Duke head coach Mike Elko recently accepted the same role at Texas A&M. 

Beyond merely staying healthy next season, teams will want to see improved decision-making and an ability to make plays within structure. He has all of the tools to be a Heisman candidate a year from now. 

DT Leonard Taylor III, Miami (Fla.)

Taylor is an athletic interior defender but he looked less explosive than he did a year ago. According to TruMedia, his pressure rate dropped from 16.2% in 2022 to 11.1% this season. He will need to do a better job of getting off blocks at the next level.

The 2024 NFL Draft will take place from April 25-27 in Detroit. More draft coverage can be found at CBSSports.com, including the weekly updated draft order, mock drafts and a regularly available look at the eligible prospects.
